reunions laking phifoiii the imiltiniiolcar ciill<, and lir cliarattcrizfcl 

 tliese fusions as uiodifitMi sexual conjugations consequent upon tlie 

 lonpr series of vt'i;etal)io divisions in llio lineage oF a sonui cell, and 

 necessary to avoitl I lie degeneration which ex[)ei'inicnt shows to 

 be attendant upon prolonged vegetative propagation. The de\ e- 

 lopiiient of the plant body may thus be regarded as endjracing 

 two phases of stimulus: lirst, tiie normal sex stimulus which 

 initiates the period of maximum cell proliferation, and, secondly, 

 this somatic nuclear union, initiating the period of maximum 

 dilTerentiation. Tissue dill'tirentialion, it was suggested, niay be 

 associated with some process of segregation subsecjuent to this 

 nuclear fusion. The separation of sex characters in the develop- 

 ment of montecious organisms was pointed to as evidence of the 

 existence of such segregation during development. 



It was finally suggested that g'l-minal moditicafions as well as 

 somatic segregations may be deriveil from a mechanism of nuclear 

 fractionizatiou and subse<iuent partial reunion in somatic cells.
